,To all whom it may concern:

Be it known that I, An'riwn R. HAvENnii,"'

a citizen of the United States, residing at Walt-ham, in the county ofMiddlesex and State of Massachusetts, have invented new and the like.

The object of the invention is to provide a cheap, simple and easilyoperated machine for fastening strips of sheet material to the cornersof trunks or for fastening such strips to the sides of trunksintermediate the corners.

The invention consists in the combination and arrangement of parts setforth in the following specification and particularly pointed out in theclaims thereof.

Referring to the drawings: Figure 1 is a side elevation of my improvedriveting machine, the same being partly broken away and shown insection. Fig. 2 is a front clevation of the same. Fig. 3 is a sectionalelevation enlarged taken on line 3-3 of Fig. 1. Fig. l is a sectionalplan taken on line 41- 1 of'Fig. 2.

tions. Fig. 11 is a vertical sectional eleva- ,tion of a modified formof work-support and trunk feeding mechanism. Fig. 12 is a plan, partlyin section, of the horizontal lever and actuating mechanism which areillustrated in Fig. '11, the lever being broken away to save space inthe drawings.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, referring to Figs. 1 to 10, inclusive, 15 is the frameof the machine consisting of a head 16 and a base 17. The

trunk or other work to be operated upon is supported upon a work-support18 which consists of a bracket having a horizontal arm 19 and aX'CItlCtll arm 20. The arms 19 and 20 are hollow and are each closed atone terminates at its upper end in a feed finger 26 fast to said feedlever and foaming, in effect, a portion thereof. The feed finger 26 isslotted at 27 to receive the cross-bar 28 of the upper end of thework-support and the arms 29, 29 of the bifurcated portion of said feedfinger are provided with corrugations or teeth 30 upon their upper edgeswhich bear against the under surface of the trunk 24 during the feedingoperation. The feed lever 25 (Fig. 4) is slidably mounted upon a block31 which, in turn, is pivoted on a stud 32 which adjustablelongitudinally of the vertical arm 20 and is clamped there- ,to by meansof a nut 33 which has screwthreaded engagement with the stud 32. Thestud 32 terminates at one end thereof in a projection 34 which projectsinto a slot 35 in the plate 22, and adjacent to the slot 35 is a seriesof lines forming a scale numbered from 0 to 60 which indicates thelength of .feed imparted-to the feed finger 26 when vthe projection 34is in line with these different lines of the scale, (Fig.1).

A combined rocking and longitudinal motion is imparted to the -lever 25by a lever 36' which is connected thereto by a pin 36' and said lever 36is slidable longitudinally thereof'upon a block 37, said block beinpivoted driving shaft 49. The main driving shaft 'meshing into a bevelgear 43 fast to a vertical shaft 44 which is journaled in bearings 45',46 in the base and head 17 and 16, respectively. A bevel gear 47 is fastto the upper end of the shaft 44 and meshes into a bevel gear 48 whichis fast to the main 49 is journal'ed in bearings 50, 50 in the head ofthe machine and is rotated by a clutch pulley 51 (Fig. 2).

The rivets which are to be driven into the ftrunk are placed in mass ina hopper 52, the rotary member 01 which is driven by a belt 53 andpulley 54, said pulley 54 being fast to the shaft'49. The rivets passfrom the hopper 52 down a raceway 55 to a separator slide 56, whichseparator slide isoperated to feedthe rivets one by one to the lowerportion 57 of the raceway 55 by a lever 58 pivoted at-59 to the head 16and rocked in one direction by a spring 60 and in the other direction bya projection 61 upon a-link 62 to which a reciprocatory motion isimparted as hereinafter described. The rivets pass one by one in amanner well known to'those skilled in the art from the lower portion 57is. fastened to a slide 66. The slide- 66 is of the raceway into a rivetholder 63. This rivet holder is made in two parts 64, .64, eachsupported upon aspring arm which guided in ways 67 in the head of themachine.

The driver .68 is fast to a driver bar 69 which is guided. in ways 7 0in the head of the machine and has a reciprocatory motionimpartedthereto by a pairof toggle links 71 and 72. The link 71 ispivoted at 73 to the upper end of the driver bar 69. The link 72 ispivoted at one end thereof upon an eccentric 74 formed upon a stud 75which is journaled to rotate in the head 16. .(see Figs. 2 and 3). Thestud 75 can be rotated and locked in different positions by a'handle 7 6which carries a spring-actuated 1 locking pin 77 adapted to be forced bythe spring 78 into any one of the holes 79, 79 in the locking plate 80which is fastened to the head 16. The links 71 and 72 are con nected bya pin 81 to the link 62, the other end of said link 62 being pivoted toa crankpin 82' fast to a disk 83 which, in turn, is fastened to theshaft 49. Thus, by the r0 .tation ofthe crank-disk 83and its crank-pin82 a reciprqcatorymotion is imparted to the link 62 which, in turn, 72andflli pon their pivots 74 and 78, re.- spectiveiy,thus imparting areciprocatery motion to the driver bar 69 and to the driver 68.

rocks the links- The rivet holder slide 66 is moved upwardly in its ways67 by a spring 84 (see Fig. 1). It. is moved downwardly by the driverbar 69 which is adapted to engage a pin 85 as said driver bar descends(see Figs. 9 and 10). The pin 85 is mounted to slide transversely of therivet holder slide 66 and has a reciprocatory motion imparted theretotransversely of said slide by a lever 86 pivoted at 87 to said slide.The lever 86 has an arm 88 thereon which projects downwardly'into a slot89 in the pin 85.

When the parts are in the position illustrated in Fig. 9, it will beseen that the pin 85' is held in such position that it will be engagedty the driver bar 69 as said driver bar descends. This will carry therivet holder downwardly, together with the rivet holder slide 66, untilthe portion 90 of the lever 86 engages the top of a stationary stop 91,when said lever 86 will be tipped, by its engagement with-the stop, fromthe position illustrated in Fig. 9 relatively to the slide 66 to thatillustrated in Fig. 10, the head or flange 92 upon the stop 91 enteringat this time a notch 93 in the lever 86, and the lever being tipped uponits pivot will move the locking pin- 85 out of engagement with thedriver bar 69, which'will then continue its downward movement until ithas driven the rivet out-from between the two spring supported sides ofthe holder 63 and through the strip 94 and the side of the trunk 24, andhas clenched the rivet 95 against.- the anvil 23. Upon the reverse I110-tion, when the driver bar 69 is moved upwardly sufiiciently to clear theright hand end of the pin 85 (Fig. 10) a flat spring 96, which bearsagainst the outer end of the pin 85, will drive said pin forward or tothe right (Fig. 10)., to the position illustrated in Fig. 9, thusdisengaging the lever 86 from the head 92 of the stop 91 and allowingthe rivet holder slide 66 to be moved upwardly by its spring 84.

When a corner piece 94 is being fastened to the trunk 24, as illustratedin Fig. 10, it is held firmly in position against the outer surface ofthe trunk by a presser foot of the style illustrated in Figs. 7 and 10,in which the presser foot 97 has an angle plate 98 at the bottom thereofwhich bears against the top and side of the corner piece 94, as clearlyseen in Fig. 10. This angle plate "98 is clamped to the lower end ofasleeve 199 by a nut 100 which has screw threaded engage ment with aprojection 101 at the lower end of the sleeve 99. -The sleeve 99 ismounted to slide vertically upon a stud 102 which, in

turn, is adapted to slide within a vertical rea cess 103 in the head 16.of the machine (see Fig. 5). A spring 104 encircles the sleeve 99 andbears at its lower end again 105 upon said sleeve, while at it p itbearsagainst a cross-pin 166 which is of-the machine. A s prin to the slidingstud 102 and projects through slots 107 in diametrically op osite sidesof the sleeve 99. The sliding stud 102 may be moved 'upwardly ordownwardly by means.

of a lever 108 which is connected to said slide by a pin 109 and ispivoted at 110 to the head of the machine. Upon the lever 108 is mounteda locking latch 111 whichis pivoted at 112 to the lever 108, one end ofsaid latch 111 being provided with a notch 112' adapted to engage a rib113 upon the head 111 holds the free notched end of theloc ring latch111 in engagement with the rib 113 when the parts are in the positionillustrated in Fig. 9, thus locking the'presser foot downwardly andclamping the corner piece 94 to the trunk 24 itbeing understood thatwhile in this position the spring 104 will yield slightly during thefeedin of the trunk along he'- n'eatluthe presser oot plate 98.

The PIGSSGI' fOOt late illustrated in Fig.

8 is substantially t e same as that illusriveted to' a portion trated inFig. i as to the manner in which it is supported and actuated, butdiffers therefrom in that it is slotted upon its under side to straddlea flat strip 114, as seen 'in Fig. 8, the portions 115, 115 of saidpresser foot extending down and along the opposite edges of the strip,114 and thus forming a guide'for said strip as itais being I of the.trunk intermedi- -ate the corners' I i The general operation of themechanism hereinbefore specifically described is as follows: The trunk24 is placed with one cor- 1 ner thereof esting upon the vertical arm 20of the wor support 18 as illustrated in Figs. 5and 10. The operatorplaces the corner strip 94 on the corner of the trunk and lowers thepresser foot to the position illustrated in Figs. 9 and 10 and-clampsthe same in that position by forcing the lever 108 downwardly until thenotched portion 112',of the locking latch 1.11 drops in beneath the rib113 onQthe head of the machine, as illustrated in Fig. ,9. He thenthrow: the elutolrinto pperation by means of "a ti eadle" (not shown inthe drawings) which op tes a rod 116 (Fig. 1), this rod, in turn,opcratinga clutch lever 117. The clutch pulley, 51 is thus locked to theshaft 49 ,and rotates the saipla, causing the driver bar'69 tojbe mgved'qlo wm ardly by the links 62,7 1,- and "72, and as said driver barmoves downwardly with its drider, it carries with it the rivet holder63, with one of the rivets 95 therein, until the under side of the rivetholde r n'early touches the upper surface 5f thefstrip 94.." At thistime the portion '90 uponth'e" lever 861will engage the flange 92 uponthe'S'tOP 91 and throw the locking pin 85 out of engagement with thedriver ,bar 59 and the'flange 92 will project into the notch-93 upon sad lever 86 and thedownward motion of the rivet holder and the slide 66will be stopped. The downward movement if the driver bar 69 and thedriver 68 will, however, continue and the rivet will be driven out frombetween the two sides of the rivet holder, down through the angle piece94.- and through the side of the trunk until the ends of the bifurcatedrivet are turned by the anvil andblehched upon the inner surface of thetrunk 24. As the driver bar moves up from the position illustrated inFig. 10 toward that illustrated in Fig.

'9, the lower end of the driver'bar will pass upwardly above the in 85and said pin then being released Wlll be moved forward or toward theright (Fig. 19) by the flat springADG and will tnus free the lever 86from the stop 91. After this has been accomplishedthe spring84= will actto carry. the rivet holder slide 66 and the rivet holder thereonupwardly to its uppermost position as illustrated in Fig. '9. As. soonas the driver bar starts up the trunk is fed for; ward bythe lever 25which is so timed as to be move upwardly into engagement with be movedtoward the left (Fig 1) to feed the trunk and strip forward in order toreceive another rivet. The combined reciprocatory and rocking movementis imparted to the lever 25 by the lever 36, eccentric 39 and shaft 40.The operation of alternately driving the rivet and feeding the trunk isrepeated until the entire strip has been attached to. the corner ofthetrunk, whereupon the operator stops the machine by releasing thetreadle and throwing out the clutch.

It, will be seen in the form of my invention illustrated in Fig. 1 thatthe trunk can be fed along the work-support toward the head 16 and base17 only so far as the length of the :horizontal arm 19 will allow and,therefore, for longer corners of the trunk another style of arm andmechanism for feeding said .trunk is used, whereby said trunk, insteadof being fed toward the head 16 and base 17, will be fed transverselythereof, the rest of the mechanism of the machine remaining the same andperforming the same functions as hereinbefore described, and in Figs.'11 and 12 I have illustrated the modified form whereby it is possibleto feed the trunk transversely .of the head and base and trans: verselyof the horizontal arm of the worksupport. Referring then to Figs. 11 and12 it will be seen that 18 is the work-support having a horizontal arm19 and a' vertical arm 20', the work-support being fastened to the base1.7. The shaft 40 has a cam 11S fast thereto and working between thejaws. 119, 119 on one end of a lever 120 which is pivoted upon a pin 121fast to a block 122, the block 122 being, ,Lturn pivotally mounted upona stud fast to the 5119 the inner surface of thetrunk and then to Thecam 118 thus imparts a rocking motion to the lever 120 in a verticalplane and about the pivot 121.. A rocking motion in a horizontal planeabout the pivotal stud 123 is also imparted to the lever 120 by a cam124: which engages a cam roll 125 journaled upon the lever 120. Thelever 120 is connected by a universal joint 126 to the lower end of alever 127 which lever is slidable longitudinally thereof upon a block129 which,in turn, is pivoted upon a stud 128. The stud 128 isadjustably fastened to the vertical arm by a nut 130, so that the lever127 can slide longitudinally thereof upon the 1;; block 129 and can rockabout the stud 128 as a pivot, thus imparting a compound. four motionfeed to the upper end of'the lever 127 similar to that hereinbeforedescribed with relation to the lever 25, except that in this 20 case thelever rocks in a plane extending transversely of the horizontal arm .19,

whereas in the former case said lever rocked in a plane extendinglongitudinally of the arm 19'. The operation of the machine otherwise isthe same, as tothe driving and feeding of the rivets, in the form of myinvention illustrated in Figs. 11 and 12 as in the form of my inventionillustrated in Fi 's. 1. to 10, inclusive.

,30 ft will be understood that the thickness of the sides of the trunk24 or of the corner strips 9 1 may vary, but that the inner face of thetrunk willalwa'ys occu' y the same position relatively to the anvi andto the feed finger; Therefore, it follows that for different thicknessesof trunk and strip, where different lengths of rivetare employed, inorder to obtain. the same clench of the rivet on the inner face o'f-thetrunk,

40 the point at which the lowermost end of the driver'must stop and the,point at which the lowermost end of the rivet holder must stop willvary. To compensate for this variation, the eccentricstud 74 is utilizedto determine the lowermost point at which the lowermost end of thedriver will stop, said eccentric stud 74 beingset and locked indifferent positionsby means of the' handle 76 and its" locking pin 7,7,and the-lowermost position .50 of the rivetholder is regulated by meansof the stop 91 which has screw-threaded adjustment with a bracket 91 andis locked thereto by a set-nut 91 If the thickness of the trunk isgreater in one case than another, then the stgp 91 is screwed upwardlyso that the pin-"$5k may be. thrown out sooner and thus stop therivetholder slide 66 and rivet f holder 63 at a greater distance from theanvil or at a greater distance from the inner hoo fapeof thewhichgbea'rs against the wonlr-snpport. In thecase of the'driver-bar anddriver, itthe thickness of the trunk is increased, then the handle 76 ismoved up WardlyQIfifiWflIfd the right (Fig. 5), thus no raising theeccentric portion of thestud 74f 5. A machine for riveting stripsi justably fastened-to said work-sup-portupon and hence raising thelowermost end of the driver to correspond to the increased thicl ness ofthe trunk which is being riveted.
